CCNA-Level Enterprise Network | Cisco Packet Tracer | VLANs | OSPF | DHCP | Security
This project demonstrates the design and implementation of an enterprise-level Hospital Management Network using Cisco Packet Tracer. The network is designed to support secure, scalable, and efficient communication between multiple hospital departments across Head Office (HQ) and Branch Office locations.
The project follows real-world enterprise networking standards, focusing on routing, switching, security, wireless networking, and WAN technologies commonly used in hospital IT infrastructures.
- Design a scalable and secure hospital network
- Implement departmental network segmentation
- Enable secure inter-department and inter-branch communication
- Simulate real enterprise services and security mechanisms
- Gain hands-on experience with Cisco routing & switching concepts
- Hierarchical Network Design
- Core Layer
- Distribution Layer
- Access Layer
- Separate networks for:
- Hospital Departments
- Server Network
- WAN / ISP Connectivity
- Branch Office Network
HQ Departments
- MLOCS
- MER
- MRM
- IT
- CS
- HQ-GWA
- Server Side (DHCP, DNS, Web, Email)
Branch Departments
- NSO
- HL
- HR
- MK
- FIN
- BR-GWA
Each department is logically separated using VLANs for better security and performance.
- ✅ Hierarchical Network Design (Enterprise Model)
- ✅ VLANs for departmental segmentation
- ✅ Inter-VLAN Routing using SVI (Layer 3 Switch)
- ✅ Static IPv4 Addressing & Subnetting
- ✅ DHCP Server for dynamic IP allocation
- ✅ NAT Overload (PAT) for internet access
- ✅ Access Control Lists (ACLs)
- ✅ Port Security on access switches
- ✅ Secure device management using SSH
- ✅ WLAN configuration using Access Points
- ✅ Site-to-Site IPsec VPN (HQ ↔ Branch)
- ✅ ISP connectivity simulation
- ✅ Host and end-device configurations
- VLAN isolation
- ACL-based traffic filtering
- Port security to restrict unauthorized devices
